Here you go:
cat /sys/power/mem_sleep
[s2idle]
journalctl --boot 0 | sed -n -r "/Starting.+Suspend/,/Finished.+Suspend/p"
shows nothing. But I haven’t put my laptop to sleep today. I’ll reboot (software updates just hit) and be back…
I rebooted, put the laptop to sleep (using the action button), closed and opened the lid and ran the command again:
